You can now watch some shows on Netflix in 4K Ultra HD resolution.

Netflix confirmed on Sunday that it started streaming 4K versions of its Emmy-nominated House of Cards original series, as well as "some nature documentaries." The streaming service provider first announced its 4K plans in December, when it revealed a 4K rollout would begin as soon as 2014.

Don't get too excited, though. You can only watch Netflix's 4K streaming video on 2014 4K TVs with a built-in H.265/HEVC decoder. If you're lucky enough to own one of those, be aware that you might see some compression. The high-resolution streams are encoded at about 15.6Mbps, according to HDTV Test.
